Tobiyas When you brought up that they flickered more and more significantly over time, were they flickering low to a point it resembles like a circuit overload? Etc ; sudden rapid dimmed light flickering over 3~ 4 seconds intervals where it may even be visually percievable at times, and suddenly brightened up again and repeat?
At first, the amplitude of the peaks just increased until the flicker eventually became 100% in a 120 hz pattern that I could feel as pain, but couldn’t “see.” I needed the meter. Later, the bulbs started to be off mostly, regularly flashing briefly on at a frequency around once a second.
I’m curious about whether all LED bulbs flicker more as they fail or if something else can happen. Is the failure mechanism an accident or is it being engineered? I just learned about the Phoebus Cartel - apparently early incandescents lasted too long so to boost sales starting in the 1929d and 30s the lighting industry started to engineer in failure at 1000 hours and fine each other for exceeding that. https://www.npr.org/2019/03/27/707188193/the-phoebus-cartel
[https://www.newyorker.com/business/currency/the-l-e-d-quandary-why-theres-no-such-thing-as-built-to-last] The Phoebus cartel broke up, but limiting the life of a incandescents continued. I wonder what the practice is for LEDs.
